For a given substance, one specifc temperature and pressure at which all three phases of that substance can exist in thermodynamic equilibrium.
1 of 6
Phases
A phase of matter is its state (solid, liquid or gas).
2 of 6
Thermal Equilibrium
A state in which there is no net flow of thermal energy between the objects involved, that is, objects in thermal equilibrium must be at the same temperature.
3 of 6
Celcius Scale
A temperature scale with 100 degrees between the freezing point and the boiling point of pure water (at atmospheric pressure 1.01 x 10^3 Pa).
4 of 6
Absolute Temperature Scale
A scale for measuring temperature based on absolute zero and the triple point of pure water, with gradations equal in size to those of the Celcius scale; unit Kelvin (K).
5 of 6
Thermodynamic Temperature Scale
A scale for measuring temperature based on absolute zero and the triple point of pure water, with gradations equal in size to those of the Celcius scale; unit Kelvin (K).
